Assignee:

Chiron Corporation - Emeryville CA

International Classification:

C12N 1500

US Classification:

4353201, 536 231, 536 2372, 4241841, 4241851, 4241871, 4241881, 4242071

Abstract:

The present invention relates to the efficient expression of HIV polypeptides in a variety of cell types, including, but not limited to, mammalian, insect, and plant cells. Synthetic expression cassettes encoding the HIV Gag-containing polypeptides are described, as are uses of the expression cassettes in applications including DNA immunization, generation of packaging cell lines, and production of Env-, tat- or Gag-containing proteins. The invention provides methods of producing Virus-Like Particles (VLPs), as well as, uses of the VLPs including, but not limited to, vehicles for the presentation of antigens and stimulation of immune response in subjects to whom the VLPs are administered.

International Classification:

C07H 2104

US Classification:

536 2372, 536 231, 435 6, 4353201

Abstract:

Polynucleotide encoding modified HIV Env polypeptides are disclosed. The Env polypeptides are modified in the region of amino acids 420-436 so as to expose at least part of the CD4 binding region. Methods of diagnosis, treatment and prevention using the polynucleotides and polypeptides are also provided.
